RANSOM H. SARGENT, OF TITU-SVILLE, PENNSYLVANIA, ASSIGNOR OF ONE- FOURTH TO JAMES L. DUNN, OF SAME PLACE.

OIL AND GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 403,447, dated May 14, 1889.

Application filed August 15, 1888. Serial No. 282,773. (No model.)

To (LZZ whmn it 'nw/g concern.-

Be it known that I, RANSOM II. SARGENT, a citizen of the United States, residing at Titusville, in the county of Crawford and State of Pennsylvania, have invented new and useful Improvements in Oil and Gas Burners, of which the following is a specification.

This invention relates to improvements in oil and gas burners; and it consists in certain novel features hereinafter described and claimed.

I11 the accompanying drawings, Figure 1 is a side elevation of my improved device, a portion of a steam-boiler being shown to illustrate the proper operative position of my improved burner. Fig. 2 is a vertical section of my improved burner. Fig. 3 is a vertical section on the line 99 a" of Fig. 1. Fig. 4 is a detail view of the mixing-tube and the check connected thereto.

Referring to the drawings by letter, A designates a casting comprising a horizontal plate, B, the integral flanges C, depending from the underside of the said plate, and the superheating-chamber D on the upper side of said plate and formed integral therewith. The plate B is provided with a central opening, E, and the superheating-chamber D surrounds this opening. This superheatingchamber D is provided with a circular opening, F, in its upper side, which is smaller than the opening E and arranged concentrically with it, and the inner side of said chamber is thus given a substantially conical formation. 0n the front side of the superheating-chamber I providea bracketor keeper, G, in which is secured the lower end of a spreader, II. The said spreader consists of a metallic plate having one end bent downward to engage the keeper G, and its central portion extending inward from said downwardlybent end over the superheating-chamber to near the opening F in said chamber. The said spreader then projects upward and inward, forming a substantially L-shaped hood, I, which projects over the said opening F.

By the arrangement of the spreader as described it may be readily placed in position or detached, as occasion may require, even when the furnace is in use.

The plate B is provided near the depending flanges O with small bolt-holes J, through which securing-bolts K project, the heads of said bolts being secured in lugs L, projecting from the side of a small box, M. This box M is further provided on its side with stops or offsets N, which, when the box is drawn upward by the bolts J, impinge against the flanges U, and thereby serve to limit the upward movement of the said box. The sides of the said box are, furthermore, arranged slightly closer together than the flanges C, so that spaces or openings 0 will be formed between the sides of the said box and the said flan ges when the box is secured in position.

P designates a steam-inlet pipe, which enters the rear side of the superheating-chamher and communicates with the said chamber.

Q designates a pipe leading downward from the bottom of the superheating-chamber, near the front end of the same, into the combustion-chamber formed by the box M, the plate B, and the flanges C. The lower end of this pipe Q communicates with a horizontal pipe,

R, which extends inward through the said combustion-chamber and has its inner end in communication with a chamber or check, S.

T designates the oil or supply pipe, which enters the rear flange, O, and passes into the combustion-chamber. \Vithin the said combust-ion-chamber this oil-supply pipe T is bent downward and then forward and communicates with the rear side of the chamber S. This chamber is provided with an interior partition, U, which separates the ends of the 8 5 pipes leading into the said chamber. From the upper side of this partition projects a small vertical nipple, V, and from the upper side of the chamber projects the tube W, the said tube extending a slight distance above the nipple V, and being arranged at about the center of the opening in the plate B.

Such being the construction of my improved burner, its operation is as follows: The steam and oil supply pipes are connected with a 5 suitable source of supply, and the steam will then enter the superheating chamber and pass through the same and the pipes Q to the chamber. The oil will pass directly to the said chamber and will rise through the tube.

The superheated steam and the oil are ignited at the upper end of the tube and the device is ready for use. As the steam flows through the superheating-chamber it will be broken up into its original constituents, (hydrogen and oXygen,) which will pass through the chamber, and by reason of their own expansible force will rise through the nipple and the tube, thereby drawing the oil up through the tube and atomizing the same by uniting with it. The heat from the flame at the upper end of the tube acts directly on the inner conical surface of the superheatingchamber, and thereby heats the same to a high degree, and consequently breaks up the steam, as before stated. The draftnecessary for effective combustion is supplied by air passing through the spaces between the box M and flanges O, and this air, coming in contact with the burning oil and hydrogen gas, supplies the necessary oxygen to support combustion, and thus produce a very intense flame, so that the boiler or furnace to be heated can be quickly raised to the desired temperature. The heat rises through the central opening in the superheating-chamber and is deflected to all sides by the spreader, so as to be applied to all parts of the fire-box of the boiler or furnace.

In practice my device rests in the fire-box of a boiler-furnace or an ordinary cookingstove, as may be desired, and as will be readily understood upon reference to Fig. 1.

While I have described the use of steam and oil, it is equally as well adapted for the use of compressed air and oil. When compressed air and oil are used, the compressed air is forced through the steam-supply pipe and the oil is sent through the oil-supply pipe, the operation of the device being the same as when steam and oil are used.

From the foregoing description it will be seen that I have provided a very simple burner,

in which all of the heating units of the air,

the steam, and the oil are utilized, and by which a very powerful heat is easily produced.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

.1. The herein-described casing for hydrocarbon-burners, the same comprising the annular superheatin g-chamber having laterally outward-extending base provided with downwardly-extending flanges formed integrally with said chamber, the bottom box having vertical sides and laterally outward-extendin g lugs to support the flanges of the superheating-chamber at a distance beyond the walls of said bottom for the passage of air in a direct upward direction between said walls and flanges, and the connecting-bolts, in combination with the steam and oil pipes, the chamber having a diaphragm or partition forming separate compartments with which said steam and oil pipes are connected, the tube extending upwardly from the oil-compartment, and the nipple secured to the diaphragm connected with the steam-compartment and extending within the tube, substantially as and for the purpose herein set forth.

2. In a hydrocarbon-burner, the combination, with the superheating-chamber provided with a bracket or keeper on its front side, of an inverted- L-shaped shield or deflector having a shank, whereby it is mounted detachably in said keeper or bracket, so as to be conveniently accessible, as herein described, and for the purpose set forth.

In testimony that I claim the foregoing as my own I Have hereto aflixed my signature in presence of two witnesses. I

RANSOM H. SARGENT.
